ANCHOR-BOLT.

SPECIFICATION forming part of Letters Patent No. 549,069, dated October29, 1895.

' Application filed February 23,1895. Serial in 539,342. (No model.)

To aZZ whomjt may concern:

Be it known that I, CHARLES H. LEVER, a citizen of the United States,residing at Chicago, county of Cook, and State of Illinois, havinginvented a certain new and useful Improvement in Anchor-Bolts; and Ideclare the following to be a full, clear, and concise deto enter acommon bolt from the desired direction.

Referring to the drawings, Figure 1 shows my device in elevation as itappears when being passed through a hole in any desired object. Thedrawing shows a vertical section of a fragment of block. Fig. 2 is aview similar to Fig. 1, showing the anchor-bolt passed through the holeand the lower end of the anchor-block resting on the top of the blocknear the edge of the hole. Fig. 3 shows my device as it finally appearswhen in use. Fig. 4 is a top plan View of the anchor-block. Fig. 5 is abottom plan view of the anchor-block. Fig. 6 is a vertical section ofthe anchor-block on the line 6 6, Fig. 5.

Similar letters refer to like parts throughout the specification anddrawings.

My device consists of a common bolt and a specially-formed anchor-block,that will hereinafter be more particularly set forth and claimed.

I mount upon an ordinary bolt A, having the squared portion A beneaththe head thereof, an anchor-block B, provided with an oblong opening B,designed to receive the bolt A. The anchor-block B is also provided withtwo oppositely-curved concaved recesses 13 B adapted to receive the boltA, said recesses beginning at the opening B and vanishing at oppositesurfaces of the anchor-block B, as shown in Figs. 4, 5, and 6. Theanchorblock B is also provided at one end with a hook 13 adapted to hookover the head of the bolt A, as shown in Figs. 1 and 2. The boltAisscrew-threaded for any desired portion of its length and has mountedthereon an ordinary nut C.

The operation of my invention will be readily understood. Place the hookportion B of the anchor-block B upon the head of the boltA and pass samethrough a previously-prepared hole D in the block D, Fig. 1, then beginto withdraw the bolt, holding same so that the lower end of theanchor-block B will contact the upper surface of the block D, as shownin Fig. 2, when it will be arrested against further downward movement.The downward movement of the bolt A will cause the removal of the headof the bolt A from the hook B of the anchor-block B, allowing saidanchor-block to assume the horizontal position shown in Fig. 3.

I have made the opening B in the anchorblock oblong, so as to receivethe squared portion of the bolt A and prevent same from turningindependently of the anchor-block.

The anchor-block is provided with the concave recesses B B to allowtheanchor-block to lie as close to the bolt A as possible while beinginserted, thereby requiring a comparatively-small opening.

It will be seen that my device provides a very strong anchor, as thestrain is directly upon the head of the bolt and anchor-block. Theanchor-block is so constructed as to bear on a considerable surface oneither side of the opening.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-- 1. An anchor-bolt consisting of anordinary bolt having mounted loosely thereon, an anchor-block, providedwith a central oblong opening and a hook at one end, adapted to fit overthe head of the bolt, all substantially as set forth and shown.

2. In an anchor bolt, the anchor-block, having an oblong opening andoppositely inclined concave recesses for the reception of a bolt, saidanchor-block also having a hook formed at one end thereof, allsubstantially as and for the purpose set forth.

CHARLES H. LEVER.
